a nis shoes.

ln the manufacture of canvas shoes havingrubbersoles andofthetype calledtennisf shoes, itis the usual practice to secure a thin strip 'ofunvulcanized gum rubber, termed a y1C foxing, around the periphery ofthe bottom of the lasted shoe prior to the application of the rubbersole.v This strip has been secured in place by means of a heavy, viscousce` ment which commonly `is applied by hand, the voperator holding abrush filled With the cement in one hand While presenting the shoethereto with the other hand and turning the shoe so as to present allportions of the area to which the foxing is to be applied to the brush.The foxing is then applied tothe cement coated foxing area after whichthe rubber sole is cemented to the shoe with its edge overlapping thefoxing strip, and the sole and l'o'xingare vulcanized together.

The `proper appearance of the completed shoe depends largely upon theproper posif tioning of the foxing strip on the shoe,.the aim being tolocate the strip so that all points in its upper edge are at auniformdistance,

approximately a halfinch, from the bottom of the shoe. Furthermore, in`order't'o pro-v duce a commercially `satisfactory product, it isnecessary for the stripe of cement to coincide at its upper edge'accurately with the upper edge of the foxing strip. v In other Words,if the cement shows above the foxmg stripfthe appearance isunsatisfactory and if the foxing strip overlaps the stripe of cement,then the edge of the strip is not prop# erly secured to the shoe and theappearance not only is not satisfactory but there is danger ofaccidental tearing away of the strip On the other hand, in spite ofthese requirements, experienced operators have acquired` a skill suchthat the speed of their Work Ais very considerable.

One object of the present invention is to. provide a machine forapplying cement to the foxing areas of shoes which will pro duce Work ata speedart least as great as the ports adapted speed obtained by handWork and of more uniformly satisfactory quality.

To this end, and in accordance With a feature of the invention, theillustrated machine, Which is substantially automatic in its operation,is provided vwith an endless carrier havin@ a series of shielding shoesupto receive and to protect portions of a plurality of shoes and totransfer the shoes successively past cement-applying mechanism, theshoes being thereafter removed in turn from the carrier. Preferably, andas herein illustrated, the machine is also provided with a dryingchamber through which the coated shoes are passed in turn to dry thecoating suiiiciently so that the shoes ma be readily removed from thecarrier.

i, s has 'already been brought out, the accursite definition of theupper edge of the coated foxing' area is important to the production ofsatisfactory work and in accordance with another feature of theinvention, the illustrated shielding devices above referred to areconstructed and arranged to protect the uppers of the shoes above thefoxing areasfrom the application of cement While accurately defining theupper limits of the foxing areaso The shields may be in the/form ofplates having shoe-receivin openings corresponding in outline to the sapes of the bottoms of shoes tobe cemented, the edges of said openingsbeing curved vertically according to the 'vertical curves of the shoebottoms, Vin order that the foxing areas defined by the shields will beuniform in Width around the shoes. In order to define accurately the uper edges of the foxing areas in shoes of dibrent sizes, Worh-sup portingshields having openings of different sizes are preferably provided, theillustrated work-supporting shields being detachably secured to theendless carrier so that they may be v leadily removed and replaced whendesire Still another object of the invention is to provide improvedcement-applying means by which all `forms of cement may bereadilyprojected in aspray on parts of boots and shoese It will be understoodthat the construction force set up by a rotating applying device of anapparatus which will b e adapted to handle not only cement of mediumbody but willbeequallycapableotsprayiiigthelieavy and viscous types ofcement, which usually have been employed forVY the foxing areas ofshoes, is attended With difficulty. Furthermore, the situation isrendered even more complex when employing cement .compoundedot'Water-dispersed latex, which will hereinafter be termed simply latex,because of the fact that, While latex is thin enough for dispersion inthe form of a Ispray without great difficulty when the machine is firststarted, this action cannot be continued indefinitely because of thecoagulation which is set up Whenever the latex is subjected to pressureor friction by the handling apparatus. In accordance with still anotherfeature of the invention, the illustrated machine is provided With novelcement-spraying mechanism which utilizes the centrifugal to which thecement is delivered to break up the cement Iinto a spray for applicationto a shoe part supported in the range of the spray produced by saidapplying apparatus.

Because of the viscosity of certain types of cement, it is founddesirable to make provision for restricting the delivery of cement bythe cement-applying device, and in the illustrated apparatus a rotarycement-pro-v jecting member having a restricted delivery slit adjacentto its periphery is provided, the cement being supplied to said rotarymember for 'delivery through said slit by the action of centrifugalforce to break into a spray before it strikes the Work. Also asillustrated, a flat disk is mounted for rotation about an upright axispositioned along side of tli'e shoe supports on which are carried theshielded shoes. Cooperating with this disk is a funnel-shaped annularmember overlapping the surface of the disk and having one of its edgesadjacent to but spaced from the edge of the disk. This annular membercooperates With the disk to provide a restricted space in which cementis received for delivery and an annular peripheral slit through whichcement is projected. In order to increase the disperson of the spray,the disk is tilted with respect to its axis of rotation. Preferably, aplurality of disk cement-applying devices are provided, thecement-applying devices being located upon opposite' sides of the Worksupport so that, as a shoe is carried progressively past thelcement-applying devices, the tWo sides of the shoe are coatedsimultaneously step by step. Preferably too,a receptacle is provided forcatching surplus cement, and means is provided for returning the surpluscement to the spraying devices for reuse.

In its method aspec`t,vthe invention provides an improved method ofspraying cement on the foXing area of a shoe, the upper portion of Whichis surrounded by a shield to prevent the application of cement thereto,

whicliiseharactenzedbycausingarelative movement of translation between aspraying device andthe shielded shoe to present different portions ofthe foxing area to the spraying device. As herein exemplified, themethod comprises placing a shoe in operative relation to a shieldingdevice to protect the portion of the upper lying above the foxing areaand spraying cement on successive portions of the foxing area until theWhole of the foxing area is coated.

In order that a plurality of shoes may he readily presented successivelyto the cementing and drying apparatus of the illustrated machine, thereis provided a conveyor in the 'form of an endless carrier 10 passingover suitable Wheels 12 and l-l ournalled upon opposite en s of asupporting frame 16. This endless carrier 10, as shown in Figs. 1 and 2,is made up of a'series of parallel links 18 pivoted at their ends on theaxes of grooved rollers vE20. These rollers are received incorrespondingly shaped recesses 22 in the end Wheels and rails 2-1 areprovided along the upper run of the frame 16 which form 'tracks forthe-rollersand thereby support the carrier and the shoes thereon at apredetermined level. The axes of alternate rollers 2() also servepivotally to support side carriers Q6 having inturiied bottom flanges 28at their lower edges and outturned lips 30 and 32 at fthe ends of theirupper edges and resting on adjacent links when the carrier is travelingalong 'the rails 24. The 'inturned bottoni flanges 28 of the sidecarriers Q6 are provided machine, viewed as in Fig. 1, and to remove.

tom ot a shoe, said shield being associatedwith the shoe itself andvsurrounding the shoe to protect the upper above the toXing area. Thecombined work supports and shields have cross-rods 48 and 50 extendingacross the opening 44 and upon which the bottom of the shoe rests andthe edges of this plate at the opening are curved upwardly as at 46(Fig.

2) with respect to the plane of the Work-sup-`A port so that, when ashoe is supported on the` rods 48 and 50, the edge of the opening 44will coincide with the upper edge of the foxing area of the shoe as itsupports a shoe positioned therein., With this form of work-support, itis only necessary for the operator to deposit one shoe after anotherinthe openings of the work-supports 40 at the left end of the them fromthe work-supports at the right end of the machine, the conveyor `beingeffective automatically to present shoes to theapplying devices and toremove them therefrom.

It will be understood that the openings`44 of the successivework-supports are shaped `alternately for right and for left shoes.

The application of cement to the shoes suc- A cessively presented bymeans of the carrier 10 is eiiected by projecting the cement from apairof rotary disks 52 and 54. arranged upon opposite sides of the pathof movement of the shoe and mounted in tilted position at the upper endof shafts 56 and 58 which are journalled in the frame 16 ot the machineand in the bottom of a tank 60. These rotary members 52 and 54 aredriven at suicient speed so that they disperse the cement in the form ota 'fine spray to all sides ot the axis of each vot them. By properl vproportioning the speed of rotation to thev character and viscosity ofthe cement, the

action of centrifugal torcewill cause the cement to be distributed in afine film over the surface ot the rotating cement applying' device andthis tilmvvill b e broken up into la 'fine spray by the resistance ofthe air as so'on as it leaves the disk. The apparatus, therefore,facilitates the projection otcement inA the form of a spray without anypossibility of clogging the outlet opening of the cement applyingdevice. The cementpwhich is not used is caught in the tank Oivhich isprefera-bly shaped so that the surplus cement will drain toVV an outletpipe 62 from which it is removed by means of a suitable pumpv (notshown) and delivered again, for reuse, to

the disks through supply pipes 64 and 66, each of -Whi'cht'is providedwith a control valve 68. The shafts 56 and 58 for the oppositelydirected spraying devices are joined by means ot a crossed driving beltand power is supplied for rapid rotation ot the disks by means of anelectric motor 72, here shown as directly connected to the shaft 56. Itwill be observed 'from an inspection of Fig. 5 thatadditional dispersionof the spray in fanshaped fashion above and below the plane ot thecenter of'rotation of the disks results from the tilted position of thedisks upon their axes of rotation, this dispersion being sufficient tocoat the whole vertical extent of the 'foxing area, which is indicatedin that figure by the blackened portion 74 extending aroundl the cornerof the shoe 76 as Welll as 4 lapping relation to the disks are providedwhich cooperate with the disks to form restricted spaces provided withrestricted out-` let openings near the periphery of each disk throughwhich the .cement will be delivered. As herein shown the guards 80 arefunnelshaped'hollow frusto-conical members which aremounted directlyAupon the-disks themselves and held thereon by means ot suitablesupports 82 with their edges adjacent to but spaced from the edges ofthe disks to form a'` restricted annular delivery slit adjacent totheperiphery ot the rotary disk. rllhc restricted partially enclosed spacesprovided between the guards 8() and the disks 52 and 54 have inletopenings 84 through which cement is supplied by means of pipes 64 and 66for delivery through the peripheral openings ot the rotary members.v`

The ends of the tank 60 are cut away as shown at 86 (Fig. 3) to providea pathway above the cement in the tank along which the successive shoesmay pass, and covers 8S and 90 (Fig. 2) are provided which extend fromthe outer edges of the tank to the tracks 24 thereby partially to coverthe tank outside ot the pathway of the conveyor 10. It will he notedthat the space between the tracks is practically covered by thesuccessive work-supports 40 associated therewith, thereby givinglittleopportunity for the scattering of the cement spray into the open air. Ifdesired, the movementof the endless carrier may be' effected by means ofpower supplied from. the same motor 72' and to this end,` there is shownin Fig. l a worm and gear drive 92 for a counter shaft 94 journalled inthe frame l'which is connected by a sprocket. and driving chains 96and98 to the end wheel l2. f

lt will be observed from an inspection of Fig. v4 that the rotatingdisks 52 and 54,

l bers or annular guards 80 mounted in overthrowing a spray horizontallyin all directions, are effective to coat both sides of the shoesimultaneously as the shoe moves along the pathway between said disks.The toe end will be coated as the shoe approaches the disks, while theheel end will be coated as the shoe recedes from the disks and the upperedge of the coated area will be accurately defined by the co-action ofthe shields 40 with the shoes.

After the shoes are coated, they are carried through a dryingehamber 100provided with suitable heating means, such as stream pipes 102 andhaving entrance and exit openings which are protected by flaps 104 and106. By means of this arrangement, a sufficient proportion of themoisture or solvent in the cement is removed so that the shoes may bereadily handled as they emerge from the drying chamber and be removed bythe operator by lifting lthem in turn as indicated by the arrow 110.
